CA 2236083

A co-channel interference canceler and a method therefor. The co-channel interference canceler includes: an NTSC interference rejection filter (NRF) for removing co-channel interference from an input signal; a noise reducer for reducing noise by removing interference other than co-channel interference from the input signal; and a selection controller for generating a selection signal for selecting the NRF by determining whether or not co-channel interference exists in the signal output from the noise-reducer. Therefore, effect from interference other than the co-channel interference is minimized, so that the co-channel interference controller is reliably controlled.

L'invention est constituée par un appareil et une méthode d'élimination de parasites de canal commun. L'éliminateur de parasites de l'invention comprend : un filtre éliminateur de parasites NTSC qui sert à éliminer les parasites de canal commun dans un signal d'entrée; un réducteur de bruit utilisé pour réduire le bruit en éliminant de ce signal les parasites autres que les parasites de canal commun; et un contrôleur de sélection servant à produire un signal de sélection utilisé pour sélectionner le filtre éliminateur de parasites en déterminant s'il y a présence ou non de parasites de canal commun dans le signal de sortie du réducteur de bruit. Par conséquent, l'effet des parasites autres que les parasites de canal commun est minimisé et le contrôleur de parasites de canal commun est commandé de façon fiable.
